Sterile lemmas are produced between the fertile floret and the rudimentary glumes (4, 14, 26). The sterile lemma has not been genetically characterized and is often mistaken for a glume. The present study showed that the G1 gene is specifically involved in specification of the sterile lemma.

What is Spike and spikelet?
